Two issues with the game. First, in google chrome there seems to be no screen-lock, if you use the arrow keys the screen just scrolls down every time you press down. Secondly the colors, at first I thought it was only some kind of "fuck the color blind" sort of deal, but actually I went to the point where a square of certain score was the exact same color as one of the squares before it. It's already hard enough to keep track of the color evolution but squares of the exact same color is game-breaking. Besides form that all the rest works ok for a 2048 game.
